+ Fix flow control bug in hipe compiler that may cause

+ Own Id: OTP-13965 Aux Id: PR-1253 </p>
+ </item>
+ <item>
+ <p>
+ Fix bug in native compilation of bitstring pattern
+ matching causing erroneous runtime matching result. The
+ bug only affects code containing constant-valued segments
+ whose size is expressed in bits; it is triggered when the
+ pattern matching against these segments fails (i.e., when
+ the next clause needs to be tried).</p>
+ <p>
+ Own Id: OTP-14005</p>
+ </item>
+ <item>
+ <p>
+ Workaround in HiPE LLVM backend for a bug in LLVM 3.9.
+ The bug could cause LLVM-compiled modules to be rejected
+ during loading with a badarg exception in
+ hipe_bifs:enter_sdecs/1, but also cause corruption or
+ segmentation faults i runtime.</p>
